cowsay is confused by input with ansi colour codes

[James Dingwall]

The maxlength function to construct the bubble calculates string length including escape sequences so although the colours are printed in the output the surrounding bubble is malformed, e.g.:

$ figlet "Hello World!" | toilet -f term --metal | /usr/games/cowsay -n

This can be solved by removing the escape sequences during string length calculations by applying one of the attached diffs. I have not tested the older versions one with an older perl to be certain it is correct.
(I am aware I could switch toilet / cowsay in the pipe but with this order I get a coloured message with a black and white cow.)
